New Scheme for the Construction of Phase Shifts with Application to Nuclear Magnetic Resonance

Abstract

A semiempirical scheme is developed for the construction of phase shifts of unlimited order for the investigation of properties depending on the electron redistribution in alloys. The method utilizes a generalized free-electron potential around the solute atom, residual-resistivity data, and the Friedel sum rule. Application to the Knight shifts in a series of dilute alloys with liquid copper and solid silver as hosts leads to much better agreement with experiment than obtained previously.
